Abstract

The invention discloses a controller, a method for generating a control signal, and a device including a computer-readable medium. In some examples, a controller is configured to control a primary-side switch in a power converter circuit, and the controller includes a first node configured to receive a first signal indicating a current or a voltage through a primary side of a transformer of the power converter circuit. The controller also includes a second node configured to receive a second signal indicating a current or a voltage through a primary-side switch of the power converter circuit.The controller further includes processing circuitry configured to determine a target value for the second signal based on the first signal and generate the control signal for the primary-side switchbased on the target value for the second signal.

Description

technical field [0001] The present disclosure relates to power electronics. Background technique [0002] Power converter circuitry may receive power from an alternating current (AC) main power source (eg, the grid) and convert the power to a lower direct current (DC) voltage suitable for powering electrical loads. A power converter circuit may include safety isolation between an input side (eg, primary side circuitry) and an output side (eg, secondary side circuitry). Regulation elements of the power converter circuit (eg primary controller) may be on the primary side, but regulated parameters (eg output voltage or output current) may only be available on the secondary side of the power converter circuit. [0003] Therefore, the power converter circuit may include some kind of communication medium to send information from the secondary side to the primary side. To this end, the power supply circuit may include a safety isolation device (eg an optocoupler), but some other ...
